unfortunately camera has stopped" while using Content Provider

If I use ContentProvider in my app am getting error like "unfortunately camera has stopped" after Result_ok.This is my code:
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, MyFileContentProvider.CONTENT_URI);
startActivityForResult(i, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
How to to solve this?I don't want to save image in sd card.
This my MyFileContentProvider class:
public class MyFileContentProvider extends ContentProvider {
public static final Uri CONTENT_URI = Uri.parse("content://com.example.user.studentadmission/");
private static final HashMap<String, String> MIME_TYPES = new HashMap<String, String>();
static {
MIME_TYPES.put(".jpg", "image/jpeg");
MIME_TYPES.put(".jpeg", "image/jpeg");
}
#Override
public boolean onCreate() {
try {
File mFile = new File(getContext().getFilesDir(), "student.jpg");
if(!mFile.exists()) {
mFile.createNewFile();
}
getContext().getContentResolver().notifyChange(CONTENT_URI, null);
return (true);
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
#Override
public String getType(Uri uri) {
String path = uri.toString();
for (String extension : MIME_TYPES.keySet()) {
if (path.endsWith(extension)) {
return (MIME_TYPES.get(extension));
}
}
return (null);
}
#Override
public ParcelFileDescriptor openFile(Uri uri, String mode)
throws FileNotFoundException {
File f = new File(getContext().getFilesDir(), "student.jpg");
if (f.exists()) {
return (ParcelFileDescriptor.open(f,
ParcelFileDescriptor.MODE_READ_WRITE));
}
throw new FileNotFoundException(uri.getPath());
}
#Override
public Cursor query(Uri url, String[] projection, String selection,
String[] selectionArgs, String sort) {
throw new RuntimeException("Operation not supported");
}
#Override
public Uri insert(Uri uri, ContentValues initialValues) {
throw new RuntimeException("Operation not supported");
}
#Override
public int update(Uri uri, ContentValues values, String where,
String[] whereArgs) {
throw new RuntimeException("Operation not supported");
}
#Override
public int delete(Uri uri, String where, String[] whereArgs) {
throw new RuntimeException("Operation not supported");
}
}

Few camera action works only on Kitkat, use condition for action:
Intent i = (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT)
? new Intent(MediaStore.ACTION_IMAGE_CAPTURE_SECURE)
: new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, MyFileContentProvider.CONTENT_URI);
startActivityForResult(i, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
If still crash occur, try avoiding ContentProvider just for testing. Let me know.

Give permission for open Camera.
Give run-time permission for open Camera.

How to open pdf from asset in Android Kitkat only?

I am developing an android app where I have some pdf files stored in asset folder. On click of list items the files open through available pdf viewer. The following code runs fine in versions lower than Kitkat. But as Kitkat have its own Storage Access Framework(SAF) the code only opens the framework not the file.
FileContentProvider.java
public class FileContentProvider extends ContentProvider
{
#Override
public String getType(Uri uri)
{
return "application/pdf";
}
#Override
public AssetFileDescriptor openAssetFile(Uri uri, String mode) throws FileNotFoundException
{
AssetManager am = getContext().getAssets();
String file_name = uri.getLastPathSegment();
if (file_name == null) throw new FileNotFoundException();
AssetFileDescriptor afd = null;
try
{
afd = am.openFd(file_name+ ".mp3");
}
catch (IOException e)
{
e.printStackTrace();
}
return afd;
}
private final static String[] COLUMNS = {OpenableColumns.DISPLAY_NAME, OpenableColumns.SIZE};
#Override
/**
* This function is required for it to work on the Quickoffice at Android 4.4 (KitKat)
*/
public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder)
{
if (projection == null)
{
projection = COLUMNS;
}
String[] cols = new String[projection.length];
Object[] values = new Object[projection.length];
int i = 0;
for (String col : projection)
{
if (OpenableColumns.DISPLAY_NAME.equals(col))
{
cols[i] = OpenableColumns.DISPLAY_NAME;
values[i++] = uri.getLastPathSegment();
}
else if (OpenableColumns.SIZE.equals(col))
{
cols[i] = OpenableColumns.SIZE;
values[i++] = AssetFileDescriptor.UNKNOWN_LENGTH;
}
}
cols = copyOf(cols, i);
values = copyOf(values, i);
final MatrixCursor cursor = new MatrixCursor(cols, 1);
cursor.addRow(values);
return cursor;
}
private static String[] copyOf(String[] original, int newLength)
{
final String[] result = new String[newLength];
System.arraycopy(original, 0, result, 0, newLength);
return result;
}
private static Object[] copyOf(Object[] original, int newLength)
{
final Object[] result = new Object[newLength];
System.arraycopy(original, 0, result, 0, newLength);
return result;
}
#Override
public boolean onCreate()
{
return true;
}
#Override
public Uri insert(Uri uri, ContentValues values)
{
return null;
}
#Override
public int delete(Uri uri, String selection, String[] selectionArgs)
{
return 0;
}
#Override
public int update(Uri uri, ContentValues values, String selection, String[] selectionArgs)
{
return 0;
}
}
The code block from where it is called:
if(android.os.Build.VERSION.SDK_INT <19) {
i = new Intent(Intent.ACTION_VIEW);
}
else {
i = new Intent();
}
/**Open PDF Forms*/
String fileName = "af1_version_7_december_2013.pdf";
i.setDataAndType(Uri.parse("content://package_name/"+fileName), "application/pdf");
try {
startActivity(i);
}
catch (ActivityNotFoundException e)
{
Toast.makeText(getActivity(), "NO Pdf Viewer", Toast.LENGTH_SHORT).show();
}
After debugging I have seen that for Kitkat the Kitkat specific code in my FileContentProvider.java is not accessed.
Please let me know if anyone have the solution to this problem. My sincere thanks in advance.
Note: This question is not duplicate as previous questions and answers were not Kitkat specefic and after my detailed search I've found that there is no solution in stack overflow to this question as of now.

Problems with ContentProvider

Welcome all
I have a content provider that must share images from getFilesDir folder. The problem is that the method openFile is never being called. What should i do to achieve it?
I'm using the solution proposed here, but with getFilesDir: Create and Share a File from Internal Storage
i'm sharing the image with this code:
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
theUri = Uri.parse("content://com.myapp.cap/img319058");
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM,theUri);
SectionManager.getCurrentActivity().startActivity(Intent.createChooser(shareIntent, ""));
The problem is that the method openFile is never being called. Instead of it, it is called the method openAssetFile but i don't want that! i want that the method openFile get's called
This is my content provider:
public class AssetsContentProvider extends ContentProvider{
#Override
public AssetFileDescriptor openAssetFile(Uri uri, String mode) throws FileNotFoundException {
return null;
}
#Override
public ParcelFileDescriptor openFile(Uri uri, String mode) throws FileNotFoundException {
File root = getContext().getFilesDir();
File cacheDir = getContext().getCacheDir();
File path = new File(root, uri.getEncodedPath());
path.mkdirs();
File file = new File(path, "file_"+uri.getLastPathSegment());
int imode = 0;
if (mode.contains("w")) {
imode |= ParcelFileDescriptor.MODE_WRITE_ONLY;
if (!file.exists()) {
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
}
if (mode.contains("r"))
imode |= ParcelFileDescriptor.MODE_READ_ONLY;
if (mode.contains("+"))
imode |= ParcelFileDescriptor.MODE_APPEND;
return ParcelFileDescriptor.open(file, imode);
}
#Override
public int delete(Uri uri, String selection, String[] selectionArgs) {
return 0;
}
#Override
public String getType(Uri uri) {
return null;
}
#Override
public Uri insert(Uri uri, ContentValues values) {
return null;
}
#Override
public boolean onCreate() {
return false;
}
#Override
public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
return null;
}
#Override
public int update(Uri uri, ContentValues values, String selection, String[] selectionArgs) {
return 0;
}
}
Thanks for your help

Way to get ParseObjects to custom Search suggestions in Android

I want to ask, if is there some way to get ParseObjects to Search suggestions-box in Android. I've succesully created recent-query suggestions and it worked well. But right now do I need to put there one string collection from Parse.com while the user is typing -show results, which contain the query which is being typed. I am kind of desperated because I've been searching for it for a week and no result.
Do you have any idea, how to accomplish that?
My in normal ParseQuery in SearchActivity:
ParseQuery<Animal> squery = ParseQuery.getQuery(Animal.class);
squery.whereMatches("animal", query, "i");
squery.findInBackground(new FindCallback<Animal>() {
#Override
public void done(List<Animal> animals, ParseException error) {
if(animals != null){
nAdapter.clear();
for (int i = 0; i < animals.size(); i++) {
mProgressBar = (ProgressBar) findViewById(R.id.search_loading_animals);
mProgressBar.setVisibility(View.INVISIBLE);
nAdapter.add(animals.get(i));
}
}
}
});
SuggestionAdapter to which do i need to implement the ParseQuery:
public class SuggestionProvider extends ContentProvider {
private static final String TAG = "SuggestionProvider";
private static final int SEARCH_SUGGESTIONS = 1;
private static final UriMatcher sURLMatcher = new UriMatcher(
UriMatcher.NO_MATCH);
static {
sURLMatcher.addURI("*", SearchManager.SUGGEST_URI_PATH_QUERY,
SEARCH_SUGGESTIONS);
sURLMatcher.addURI("*", SearchManager.SUGGEST_URI_PATH_QUERY + "/*",
SEARCH_SUGGESTIONS);
}
private static final String[] COLUMNS = new String[] {
"_id",
SearchManager.SUGGEST_COLUMN_TEXT_1,
SearchManager.SUGGEST_COLUMN_INTENT_ACTION,
SearchManager.SUGGEST_COLUMN_QUERY
};
public SuggestionProvider() {
}
#Override
public boolean onCreate() {
return true;
}
#Override
public Cursor query(Uri url, String[] projectionIn, String selection,
String[] selectionArgs, String sort) {
int match = sURLMatcher.match(url);
switch (match) {
case SEARCH_SUGGESTIONS:
String query = url.getLastPathSegment();
MatrixCursor cursor = new MatrixCursor(COLUMNS);
String[] suffixes = { "", "a", " foo", "XXXXXXXXXXXXXXXXX" };
for (String suffix : suffixes) {
Toast.makeText(getContext(), "", Toast.LENGTH_SHORT).show();
addRow(cursor, query + suffix);
}
return cursor;
default:
throw new IllegalArgumentException("Unknown URL: " + url);
}
}
private void addRow(MatrixCursor cursor, String string) {
long id = cursor.getCount();
cursor.newRow().add(id).add(string).add(Intent.ACTION_SEARCH).add(string);
}
#Override
public String getType(Uri url) {
int match = sURLMatcher.match(url);
switch (match) {
case SEARCH_SUGGESTIONS:
return SearchManager.SUGGEST_MIME_TYPE;
default:
throw new IllegalArgumentException("Unknown URL: " + url);
}
}
#Override
public int update(Uri url, ContentValues values, String where, String[] whereArgs) {
throw new UnsupportedOperationException("update not supported");
}
#Override
public Uri insert(Uri url, ContentValues initialValues) {
throw new UnsupportedOperationException("insert not supported");
}
#Override
public int delete(Uri url, String where, String[] whereArgs) {
throw new UnsupportedOperationException("delete not supported");
}
}

How to put a video file in android custom content provider
